How many chips does one game generally take?

Some go up to 8-10

I would say most are between 3 and 5 chips

3-6 credits its on a card but you get to choose how money you put in the card so when that runs out you can put more money on the card or leave

You buy a card that has points on the card. Depending on how much you want to spend, is how many points you will have available. The games generally use between 3.6 and 9.9 points.
